You might be interested in my system. I designed it 2012, and started developing 2014, and Bitnation have acquired it and it's received some media attention.

It uses a concept called dividend pathways. Each transaction you make creates or adds to one of these pathways. Each pathway facilitates a flow of dividends up to the amount that was transacted to create the pathway. If you send me $100, up to $100 in dividends will flow through that pathway.

The dividends are divided on everyone that's connected through these pathways. I call this a swarm, and I've called the algorithm itself swarm-redistribution or p2p-dividend protocols.

The flow of dividends is then optimized through an optimization layer,

You can see this optimization on the GIF below in real time,

It uses an inventive structure, a sort of reward system, or you could think of it as a governance system that emerges from the feedback loops between producers and consumers,

This meta-pattern, the incentive layer, is similar to what the co-operative business movement has used for decades,

"The dividend scheme makes it more advantageous to be a loyal Coop member. As more people realize the economic benefits, the idea is that more people will become members, more people will shop at Coop and that casual customers will transform into regulars and consolidate their purchases to Coop. This will make Coop more profitable, making it possible to further improve the stores and offers to members. "

This incentive mechanism was described brilliantly in the Coinssource.com article,

“This means that consumers who want to receive basicincome will benefit greatly from seeking out corporations that are connected to basicincome.co. Therefore, corporations are incited to join the network in their effort to gain and keep costumers. Not only will this mean that consumers can create a resilient financial safety net through making active consumerist choices. The corporations will also be encouraged to take greater financial responsibility for their entire supply line.”

The system interfaces every currency online, bitcoin, ripple, NXT, and old banks too if they install an API so the app can read their ledgers. The system is like a third-party web-app, and all the user has to do is to sign their outgoing dividends, micro-payments, which could be automated if they let an app manage their password.
